Should we be concerned when Marcus Smart, James Young, Terry Rozier, R.J. Hunter and Jordan Mickey closed Monday’s loss to the Utah Jazz as a unit, and Rodney Hood was the best player on the floor?

How long until Jay Larranaga becomes a head coach in the NBA?

… OK, now to the scouting reports. We’ve seen some good and some bad from each of the young C’s in Monday’s 100-82 loss to the Jazz and Tuesday’s 76-62 loss to the Philadelphia 76ers. Below are the pros and cons we’ve seen so far.

+ Getting to the rim: Using strength to get to basket and draw fouls more often
+ Court savvy: Drawing fouls, posting up smaller defenders, etc.
+ Elite defender: Stopped quick guards Dante Exum and Bryce Cotton in tracks
+ Pick and roll: Improved orchestration of game’s most important offensive play
+ Grit: Constantly fighting for position and not afraid of contact on both ends
+ Court vision: Improved decision-making on interior passes
+ Defensive rebounding: Size and strength helps assist bigs on the glass

CONS

— Shot selection: Way too many contested long 2’s and 3’s early in the shot clock
— Shooting form: Still doesn’t square up his feet enough
— Gambler: Can be beat backdoor defensively off the ball
— Reputation: Seemingly inadvertent elbow on Jack Cooley earned a flagrant foul

Celtics rookie guard Marcus Smart struggled from the field (2-of-8), but made his presence felt across the stat sheet, finishing the day with 10 points, five rebounds, three assists and five steals.

Phil Pressey was solid as the team’s starting point guard, scoring nine points (3-of-9) while dishing out seven assists. Pressey also impressed many with a nasty crossover move on Miami rookie point guard Shabazz Napier.

Forward James Ennis led the Heat with 17 points (5-of-11) and eight boards. It was a rough debut for Napier, who scored 12 points but off a horrible 20 percent shooting percentage from the field (3-of-15) while recording just two assists and eight turnovers.

Celtics rookie guard James Young, taken with the 17th overall pick of the 2014 draft, did not play in Saturday’s game for precautionary reasons after injuring his neck in a car accident a few weeks ago.

Boston’s next summer league matchup will be on Monday, when the Celtics take on the Pacers.

After coming up short on Monday against the more talented Thunder squad in the first day of Summer League, the Celtics once again lost a lead on Tuesday in a loss to the 76ers.

Boston (0-2) came out and quickly took an early 15-3 lead in the first quarter on the strength of Tony Gaffney‘s play. After struggling in nearly 25 minutes of play on Monday, Gaffney was much more productive and filled the stat sheet against Philadelphia with 10 points, five rebounds, one assist, one steal and one blocked shot.

The 76ers (2-0), however, went on a 20-4 run through the end of the first and beginning of the second quarter to take a six-point lead. Boston was unable to cut down the deficit and went into halftime trailing by four points.

Philadelphia continued its strong play in the second half and built its lead up before eventually winning, 86-79. The 76ers had five players in double digits, with Jodie Meeks leading the way with 18 points on 6-for-11 shooting from the field and 2-for-3 shooting from beyond the arc. Jaycee Carroll and Luke Harangody each had a team-high 14 points for the Celtics, with Harangody pulling down a game-high 12 rebounds.

Boston couldn’t find its stroke from 3-point land, where it was only 1-for-11, compared to 5-for-11 for Philadelphia. The Celtics also struggled to keep possession of the ball, turning it over a total of 20 times. Point guard Oliver Lafayette committed five turnovers himself after being hounded by second-year man Jrue Holiday on the perimeter.

Boston returns to action tomorrow at 1 p.m. when it squares off against the Bobcats.

Even though the Boston Celtics already participated in the Orlando Summer League earlier this month, there were still plenty of familiar faces on hand at the 2009 Las Vegas Summer League last week:

– A relaxed Paul Pierce, who has a home in Vegas, donned a backwards Red Sox hat and sunglasses to a few games last Wednesday. Later that afternoon he was joined in the stands by Celtics GM Danny Ainge during the Milwaukee Bucks/Chicago Bulls match up.

– Celtics co-owner Wyc Grousbeck traveled to Las Vegas for the NBA’s Board of Governor’s Meeting. Grousbeck was appointed to the league’s Labor Relations Committee. While in Vegas he emphasized the Celtics commitment to winning next season to WEEI.com.

– Sam Cassell looked like the Mayor of Summer League when he made his first appearance, being swarmed by friends before sitting courtside with Celtics assistant coach Tom Thibodeau, who spent the week eyeing talent. Cassell, of course, was sporting a huge smile but this time he had traded in his uniform for a polo and khaki shorts as assistant coach for the Washington Wizards. He was at the helm on Sunday when he led the Wiz to a victory over the New York Knicks.

– Patrick O’Bryant chatted with a reporter as he was late chasing a loose ball out of bounds with the Toronto Raptors. O’Bryant averaged 11.2 points, 6.4 rebounds, and 1.6 blocked shots.

– Brandon Wallace returned to Vegas, the same place where the Celtics signed him to his first NBA contract two years ago. Wallace suited up for the Wizards after spending last season in Poland. He posted 3.5 points and 1.8 rebounds per game under assistant coach Cassell.

– Kevinn Pinkney is giving the NBA another shot after playing in Italy the past two seasons. Pinkney, who had a brief stint with the Celtics during the 2006-07 season, averaged 2.4 points and 2.6 boards for the Clippers.

– Orien Greene came to Vegas as a spectator hoping to catch on with an NBA team next season. He recently returned home from playing in Amsterdam.
